It is really difficult right now to find out where all the different
stuff relative to operation and lifecycle of an lchan is. Let's move
everything to its own file to have all the related defines and logic
together.

This API has been available since 1.0.0, and we actually require
libosmocore >= 1.7.0 nowadays, so it's totally fine using the
libosmocore API and drops the local duplicate.

The OM2000 model does not have a separate bb_transc MO, however for
compatibilty reasons we have a virtual MO that just mirrors the state of
the TRX mo. We should mark it as [Virtual] in show trx to reflect this
to the user.

This patch adds two stats which track cummulative lchan lifetime by
type TCH and SDCCH. These new counters will accomplish two things:
1) Provide a glanceable way to see if lchan durations look healthy. When
examining a site, short-lived (<5s) and long-lived (>30s) TCH lchans
are difficult to tell apart. If we only see short-lived TCH lchans,
there is most likely an RF or signaling problem to investigate. This
new counter will expose channel ages in the VTY output
2) Provide a more accurate count for Erlangs per site. Currently, we
are basing Erlangs on active TCH channel counts per stats period. This
method skews high very quickly. Each active TCH in that period
translates into the full 10s of activity. This counter should improve
accuracy by two orders of magnitude.

This reverts commit 5e2ac29703.
This patch was found to be a troublemaker regarding osmo-bsc
performance, since it's scheduling one timer every 100ms for each
channel. On a BSC with dozens of BTS, each with several TRX, this ends
up in a huge amount of timers scheduled in a tight timeframe, which ends
up in osmo-bsc spending CPU time getting in and out of the poll() main
loop.

* Don't copy features for osmo-bts and nanobts initially, wait until
BTS reported its features
* Checks for BTS features in VTY cmds: pass if features are not known
(not yet reported by the BTS), fail if the feature is missing
* Once BTS reports its features, check relevant VTY config parts again

Instead of sometimes checking against hardcoded BTS model features, and
sometimes against features reported at runtime (which only some BTS
models do):
* copy the hardcoded BTS model features to BTS features initially
* do all checks against BTS features
